Deliberate Design of Simplicity

Definition

Simplicity is not an accident. It requires deliberate choice, sustained motivation, and intentional design effort. Most systems evolve toward greater complexity unless someone is explicitly tasked and motivated to push back toward simplicity. The moment you stop designing for simplicity, complexity creeps in.

In the Book

De Bono opens the book with a striking example: "There is often a much simpler way of doing things — if you make the effort to look for it. Simplicity does not just happen." He illustrates this with the staircase arithmetic problem, where adding 1 to 100 seems tedious until you recognize a simpler geometric approach—but only if you invest the thinking effort to find it.

De Bono argues that simplicity must be treated as a primary value in design, not a secondary "nice-to-have." Most organizations and people appreciate simplicity in the abstract but rarely invest resources to achieve it. For example, creativity is widely celebrated, yet organizations make progress on it only when they designate a "nominated champion" responsible for embedding it in culture. The same applies to simplicity: "If something needs doing, then do something about it. Don't just hope that someone else will."

He proposes a National Institute for Simplicity precisely because without institutional responsibility, individual designers and craftspeople cannot shift the broader culture. Rule 1 of his ten rules states: "You need to put a very high value on simplicity"—not as a polite goal, but as a prime objective that justifies resources and time investment.

Why It Matters

This concept is load-bearing because it reframes simplicity from a passive aesthetic virtue to an active design discipline that competes with other objectives. In any organization, complexity gets added incrementally—each new feature, regulation, or stakeholder demand appears justified locally, but nobody is charged with resisting them holistically. Recognizing that simplicity requires motivated institutional effort explains why complex systems are the norm and why achieving simplicity demands deliberate opposition to natural drift. This applies across domains: software, law, procedures, user interfaces, and organizational structure.
